PROCESS OF TREATING CRACKED HYDROCARBON DISTILLATION PRODUCTS.

No Drawing.

My invention relates to a process of treating cracked hydrocarbon distillation products and especially cracked gasoline, some of which, as well known, are particularly difii- 6 cult to decolorize' and deodorize.

compounds which are not amenable to the treatment even with pyro-sulphuric acid in excessive amounts.

I have discovered that by treating cracked asoline with aluminum chloro sulphate i lSO,Cl.5H O the objectionable sulphur and nitrogen compounds are readily eliminated.

My invention consists in the steps of the 15 process hereinafter described and claimed.

I add from 2 to 5 per cent of aluminum chloro sulphate by wei ht to the cracked gasoline to be treated, epending upon the sulphur and nitrogen contents, at atmos- 20 pheric pressure and temperature, although it is preferable to raise the temperature to about 40 C. The reaction takes from to 45 minutes. From 10 to per cent water is added to the gasoline and the mixture is agitated. The aluminum chloro sulphate will combine with the sulphur and nitrogen contents of the gasoline and form a sludge and also liberate sulphur in the form of hydrogen sulphide and other volatile sulphur compounds. After the sludge is allowed to settle the clearliquid is decanted and subjected to the usual neutralization treatment-to remove the acidity of the mixture and the washing water is .se arated.

The resu tin gasoline is water clear and free from any 0 3ectionable odors.

Cracked gasoline often contains sulphur and nitrogen Application filed February 14, 1927. Serial No. 168,236.

Various changes may be made in the ste s of the process by those skilled in the art without departing from the spirit of my invention as claimed.

I claim:

1. A process of decolorizing and deodor izing cracked gasoline com rising treating the cracked gasoline with a uminum chloro sulphate.

2. A process of decolorizing and deodorizing cracked gasoline com rising treating the cracked gasolinewith a uminum chloro sulphate and water under agitation,

3. A process of decolorizing and deodor- 0 izing cracked gasoline comprising treating the cracked gasoline with aluminum chloro sulphate and water under agitation and heating the mixture to C.

4. A process of decolorizing and deo'dorizing cracked gasoline comprisin adding from 2 to 5 per cent of aluminum c 'loro sulphate and water, heating and agitatin the mixture whereby a sludge is formed, a lowing the sludge to settle and removing the supernatant liquor.

5. A process of decolorizing and deodorizing cracked gasoline comprising adding from 2 to 5 per cent of aluminum chloro sulphate and water,heating and agitatin the mixture whereby a sludge is forme allowing the sludge to settle, removing the supernatant liquor and neutralizing the acidity of the supernatant li uor.

In testimony w ereof I have signed my' name to this specification.
